Posterior Cruciate Injection: Accurate Placement

At the Centeno-Schultz Clinic stability is critical as evidenced in our SANS approach: Stability, Articulation, Neurologic and Symmetry.  Joint stability is essential for optimal clinical outcomes.

Accurate needle placement is equally important and is accomplished through direct visualization either by MSK ultrasound or x-ray or both.

The posterior cruciate ligament is large ligament in the knee that provides restraining force to straight posterior translation of the tibia relative to femur.  It originates from  anterolateral aspect of the medial femoral condyle and attached onto the posterior tibia.
VM is a 32 y/o snowboarder seen in clinic today with knee instability and pain.  MRI was significant for partial tearing of the PCL and swelling at its tibial insertion.

Below is an x-ray image of the PCL injection.   A posterior approach was utilized.  The femoral nerve and vasculature was identified by MSK ultrasound.  Thereafter a 25 gauge need was advanced into the PCL at the tibial attachment.  A small amount of contrast was injected with filling of the PCL.Posterior Cruciate Ligament

Patient hopes to return to riding soon and we are expecting snow this weekend.
